<P>PROBLEM TO BE SOLVED: To solve a problem that when a current operating point of an engine 10 is moved by operation of a speed-change ratio of an automatic transmission 18 to an operation point (optimum operating point) with a small increased amount of fuel consumption of the engine 10 associated with drive of an alternator 26 and a compressor 30, the fuel consumption of the engine 10 associated with drive of the alternator 26 and the like may likely to increase. <P>SOLUTION: An assumed electricity cost and an assumed heating cost are calculated by temporarily setting an engine rotation speed, alternator torque, and compressor torque to a plurality of mutually different values. Then, on condition that the assumed electricity cost and the assumed heating cost are equal to or below permissible upper limit values, target values of the alternator torque, the compressor torque, and the engine rotation speed are calculated for operating the engine 10 at the optimum operating point. Then, processing is performed which simultaneously outputs current-carrying signals based on the calculated target values to the alternator 26, the compressor 30, and a speed-change control ECU52. <P>COPYRIGHT: (C)2012,JPO&INPIT |
